第 12 题
你写如下的代码段去调用Win32 Application Programming Interface (API)：
string personName = "N?el";
string msg = "Welcome" + personName + "to club"!";
bool rc =User32API.MessageBox(0, msg, personName, 0);
为了实现上面的调用，你需要定义一个方法原型，请问，你会采用那个代码段进行定义？
A. [DllImport("user32", CharSet = CharSet.Ansi)]
public static extern bool MessageBox(int hWnd,String text,String caption,uint type);}
B. [DllImport("user32", EntryPoint = "MessageBoxA", CharSet = CharSet.Ansi)]
Public static extern bool MessageBox(int hWnd,
[MarshalAs(UnmanagedType.LPWStr)]String text,
[MarshalAs(UnmanagedType.LPWStr)]String caption,
uint type);}
C. [DllImport("user32", CharSet = CharSet.Unicode)]
public static extern bool MessageBox(int hWnd,String text, String caption,uint type);}
D. [DllImport("user32", EntryPoint = "MessageBoxA", CharSet =
CharSet.Unicode)]public static extern bool MessageBox(int hWnd,
[MarshalAs(UnmanagedType.LPWStr)]String text,
[MarshalAs(UnmanagedType.LPWStr)]String caption,uint type);}
答案:C

段？
A. MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new
DeflateStream(strm,CompressionMode.Compress); byte[] result = new
byte[document.Length];deflate.Write(result,0, result.Length); return result;
B. MemoryStream strm = new MemoryStream(document);DeflateStream deflate = new
DeflateStream(strm,
CompressionMode.Comress);deflate.Write(docemtn, 0,
document.Length);deflate.Close();return strm.ToArray();
C. MemoryStream strm = new MemoryStream();DeflateStream deflate = new
DeflateStream(strm, CompressionMode.Compress);deflate.Write(decument, 0,
decument.Length);deflate.Close();return strm.ToArray();
D. MemoryStream inStream = new MemoryStream(document);DeflateStream deflate =
new DeflateStream(inStream, CompressionMode.Compress); MemoryStream outStream =
new MemoryStream();int b;while ((b = deflate.ReadByte()) ! = -1) {
outStream.WriteByte((byte)b);} return outStream.ToArray();
